Abstract

A foldable jointer is composed of the hinge linked bottom plate with two lugs and a locking hook between the holes of two lugs and cover plate with a boss between said two lug, an eccentric rotary axle with drive mechanisms and screw bolts at its both ends, and the fixing rod and fixing screw bolt at the tail of said drive mechanism.

Description

technical field [0001] The invention relates to the application field of folding bicycles, in particular to a folding joint capable of connecting two sections of rods (pipes) into one; it is suitable for manpower and electric bicycles. Background technique [0002] Folding joints are mostly used on folding bicycles. The folding joints are hinges on one side of the two connecting plates connected to the rod. There is a locking device to fasten the two connecting plates together so that they cannot be opened. The joint is used on the frame, and the riding bumps are very stressful. The folding joint must not only ensure sufficient rigidity when it is closed and fastened, but also make the folding operation fast and convenient, so the locking device has to be designed The shape of the locking device outside the folding joint is irregular and thick, which makes the overall shape of the folding joint extremely asymmetrical. It is used on a well-designed folding bicycle, and the pr...

[0002] Folding joints are mostly used on folding bicycles. The folding joints are hinges on one side of the two connecting plates connected to the rod. There is a locking device to fasten the two connecting plates together so that they cannot be opened. The joint is used on the frame, and the riding bumps are very stressful. The folding joint must not only ensure sufficient rigidity when it is closed and fastened, but also make the folding operation fast and convenient, so the locking device has to be designed The shape of the locking device outside the folding joint is irregular and thick, which makes the overall shape of the folding joint extremely asymmetrical. It is used on a well-designed folding bicycle, and the protruding locking device outside the joint gives people A sense of excess, which destroys the aesthetic feeling of the whole vehicle, and may even hurt the human body. It is difficult to process, the process is complicated, and the safety is unstable

Chinese patent ZL96236902.0 provides a four-link folding joint, in which two connecting plates hinged on one side are each hinged to a connecting rod, and one end of the two connecting rods is hinged again. One end of the rod is hinged again. When the joint is closed and locked, the two connecting rods are brought together on one side of the joint to become the handle for unlocking. There are protrusions on the mating surface. This joint is used on a folding bicycle. Two connecting rods protrude from one end of the folded bicycle. The protruding two connecting rods are easily bumped. If the protruding connecting rods are damaged, the entire joint may be damaged. scrapped
